Just that really! I bought the Positive Birth company digital pack when it was only £12 but tbh I didn't watch more than a few of the videos as I then got an offer on London Hypnobirthing (Hollie de Cruz)'s online course (having already read her book/listened to her MP3s) and so I favoured that. But I see that there is an app as companion to the PBC course and wondered if it's worth having as reinforcement of the hypnobirthing techniques. They have rave reviews of it on their social media feeds but is there anyone here who has tried it and can vouch for it?
